ROOM SEALED (TYPE C) FLUE ASSEMBLY

In order to install the EcoKnight™ water heater with a type C (room sealed) flue system a flue transition kit must first be installed,

this kit is used for both C

(horizontal) and C

(vertical) flue systems. The information in this paragraph describes these flue transition

kits and their installation
